All of the information that Trulia (or Zillow, or any other real estate search page) gets comes from the public tax record from the local municipality. This information is coming from the City of Milwaukee public records data base. I did a search in the tax record for the address on Mill Rd and here's what it reads:
Building Square Feet : 2774 Year Built : 1959 Township : 8N
Bedrooms : 3 Year Remodeled : Range : 21E
Full Baths : 3 Effective Year Built : Section : 30
Half Baths : Air Conditioning : Quarter :
Total Rooms : Fireplace : Yes Pool :
Number of Stories : 1.00 Number of Units : 1 Attic : No Attic
Building Type : Ranch Basement : Full Basement
Exterior Wall : Heat : Exterior Condition : Garage :
Land Use : 8810 Single-Private Households School District : 3619 Milwaukee
Zoning : RS3 Residential Single-Family Historic Designation :
So as you can see, the City of Milwaukee tax record says the house was built in 1959; Trulia gets their information from the tax record. So to resolve the issue, you will need to contact the City of Milwaukee and have them correct the tax record.
Good luck! Please contact me if I can be of any further help with your real estate needs!

I know you stated that you have memories and pictures of the construction going on, but I want to add that during those years many home owners purchased land and built a basement and were allowed to live in the basement until the main floors were completed. Is it a possibility that this is what happened? I know that very often the year listed in the tax records is the year the home was completed and occupied.
Just a thought.
One quick walk thru would show 1949 or 1959 as construction was very different in during those 2 eras.
